Hi there,
I wrote a pretty big signal processing source code in a mixed C and C++ to run on the LCDK. By the way, I use CCS v6.01. In the source code several DSP functions from TI's dsplib are used such as FFT and dot product. Since the whole source code is big and many large data arrays are used, I allocated everything to the external memory DDR2. The code runs correctly but far too slow. The FFT and dot product modules run about 10 times slower than the benchmark. Could you advise how to customize the link command file to make the signal processing modules run faster?
Thanks very much,
Bill
